I'm trying to set up cachefilesd on an nfs share with one of my servers. It's not working.
The service is running, my drives are mounted, but it seems as if the "fsc" option is completely ignored.
My fstab (specific folder-names edited for privacy and relevancy):
$ cat /etc/fstab
# <device> <dir> <type> <options> <dump> <fsck>
UUID=c456dea4-e0c6-42f5-a206-d0ed2e94bc6a / ext4 rw,relatime,discard,data=ordered 0 1

192.168.200.20:/mnt/tank/share4 /mnt/sub/share4 nfs4 fsc,nolock,noatime 0 0
The Problem
No matter what I do, even mounting the shares manually (mount -t -o fsc...) the FSC option is not enabled:
$ cat /proc/fs/nfsfs/volumes
NV SERVER PORT DEV FSID FSC

v4 c0a8c814 801 0:64 af123987:8f7131de no
And looking at nfsstat you can see that the fsc option was totally ignored:
$ nfsstat -m

The Problem
No matter what I do, even mounting the shares manually (mount -t -o fsc...) the FSC option is not enabled:
$ cat /proc/fs/nfsfs/volumes
NV SERVER PORT DEV FSID FSC
v4 c0a8c814 801 0:55 c7d8b1ef:bb64cbde no
v4 c0a8c814 801 0:54 d9a63e22:cc9a3fde no
v4 c0a8c814 801 0:57 5a567c31:75f052de no
v4 c0a8c814 801 0:59 1673eeb4:b0583de no
v4 c0a8c814 801 0:60 9acb69e2:fb267bde no
v4 c0a8c814 801 0:58 a367662d:5b53a6de no
v4 c0a8c814 801 0:61 69fdc16c:c38e18de no
v4 c0a8c814 801 0:63 706408fe:60f412de no
v4 c0a8c814 801 0:64 af123987:8f7131de no
And looking at nfsstat you can see that the fsc option was totally ignored:
$ nfsstat -m
/mnt/sub/share4 from 192.168.200.20:/mnt/tank/share4

In a similar but ultimately unhelpful answer someone also included the output of this:
$ lsmod | grep cachefiles
cachefiles 45056 1
fscache 61440 3 cachefiles,nfsv4,nfs
and this:
$ grep CONFIG_NFS_FSCACHE /boot/config-4.15.0-20-generic
